Solution

Hint: A thin layer of metal has been put to the outside of a substance and is known as plating.

Explanation:

Metal plating creates a sacrificial coating that shields the iron from corrosion. Instead of oxidizing iron, this metal layer oxidizes itself, protecting the iron.

For plating, a metal's oxidation should be preferred over iron, and it should therefore have a lower reduction potential than iron.

Zinc has a lower reduction potential than iron and can thus be utilized for plating among the available possibilities. Galvanization is the name of the procedure.

Final Answer:

The correct answer is option $$(B)$$.
